= Configuring node pool capacity blocks on {aws-short}
7+
8+
After creating a hosted cluster, you can configure node pool capacity blocks for graphics processing unit (GPU) reservations on {aws-first}.
9+

.Procedure
11+
12+
. Create GPU reservations on {aws-short} by running the following command:
13+

14+
[IMPORTANT]
15+
====
16+
The zone of the GPU reservation must match your hosted cluster zone.
